bundler

问题 In a rails Gemfile, does gem 'capistrano' need to be inside the :development group or this there any advantage in putting it inside an arbitrary group like :tools ? 回答1: Simply put, no, it doesn't need to be, but it's good for the sake of best practices and keeping your gemsets uncluttered. The best way to do that is open for debate, but basically as long as Capistrano is available to you in the environment you're working in, it doesn't matter what groups it is or isn't associated with,

问题 At runtime, after bundler setup is complete, and groups are applied, what is the best way to programmatically check if a given gem_name is in the bundle? By reading the source, I've discovered Bundler.definition, e.g. gem_name = 'banana' Bundler.definition.dependencies.map(&:name).include?(gem_name) but unable to find documentation 1 , I don't know if this is the recommended usage. Update: It looks like Bundler::Definition#dependencies returns all dependencies, irrespective of groups. As an

问题 I know that I can specify a Ruby version in a Gemfile like so: ruby '2.0.0' However, instead of setting the exact Ruby version, I'd like to be able to specify a minimum Ruby version so that my scripts remain compatible with new version of Ruby. 回答1: Already possible since Bundler 1.12, e.g. ruby "~> 2.3.0" see here: https://github.com/bundler/bundler-features/issues/119 回答2: You could raise an exception instead: raise 'Ruby should be >2.0' unless RUBY_VERSION.to_f > 2.0 来源： https:/

问题 Using Ansible, how can I use the gem (or other) module to install a gem (in this case, bundler) such that I can run the following command without error? deployer@boxes-vm:~$ ~/.rbenv/bin/rbenv exec bundle install rbenv: bundle: command not found 回答1: Well, you can always use the bundle from the shims directory command: ${HOME}/.rbenv/shims/bundle install --deployment 来源： https://stackoverflow.com/questions/23133850/how-to-install-gems-for-rbenv-using-ansible

问题 I have a ruby app on my machine that I'm trying to deploy with a batch script. I've got everything up to the server handled. This is what I'm using: cd to/path/of/app thin start -p 3001 This works. cd to/path/of/app thin start --servers 3 As per http://code.macournoyer.com/thin/usage/, does not work. I get an error "lib/thin/runner.rb:142:in 'parse!': invalid option: --servers" Any idea why this isn't working? 回答1: On line 88 in lib/thin/runner.rb it says # Daemonizing not supported on

问题 I am using capistrano and get this error message: Please install the pg adapter: `gem install activerecord-pg-adapter` (cannot load such file -- active_record/connection_adapters/pg_adapter) I have removed the gem 'pg' from my Gemfile and bundle install d . I don't see the pg gem in my Gemfile.lock. I have also changed my production db to a sqlite3 adapter. Why is Rails 3.2 / Capistrano / Bundler asking for this? I'm not using it and not in Gemfile.lock and how do I resolve it? I am using

问题 I'm having problems deploying the Whenever gem to my production environment using Capistrano. The problem is stemming from a bundle exec whenever command that's triggering some 'missing gem' issues (yet running bundle install from the shell shows that everything is in fact there!). My feeling is that one of two things is happening: that Bundler isn't fully loading before bundle exec is being called, or that somehow there's a path issue that's running it in the wrong place. Here's what's going

问题 Problem Our deployed application has development dependencies in it. We have a lot of development dependencies. This increases the artifact size and the memory consumption in production, as all those dependencies are require 'd. Most instances are deployed in the cloud, so more memory = more money for larger instances. We would like to reduce the size/memory and make a more clear separation between the deployed artifact and the development environment. A particular focus is the need for
